Are you actually paying cash? Assuming you're using a credit card, and assuming your company isn't looking to defraud you, using a card with decent cash back makes it a nonissue and "fronting the cash" for expenses is just a way for you to get a kickback from your credit card company for using them as a payment processor for work expenses. (And kind of a net positive relative to if you had a company credit card where the company claims any kickbacks.)
